Yeah it's weird, you would think it would distract you but it doesn't. On the music thing, I've found that classical music helps me focus but other types don't. To be specific piano and violin music seems to work best for me. But that's really only when I'm writing, when I'm working on a problem podcasts, audiobooks, and music I've heard a million times already work just fine, new music will distract me though, it has to be stuff I already know.
